Cisco PS5171 QPSK
Cisco PS5180 CA
Cisco Video Networking Systems are the ultimate solution for customers who need to distribute reliable, high-quality video services over a digital broadband network.
The Cisco PS5171 QPSK Receiver/Demodulator and Cisco PS5180 CA Descrambler/Multiplexer are part of the Cisco VN 5900 and VN 5902 Video Networking Systems-high-performance video head-end solutions that receive audio and video streams from any satellite, terrestrial, or wireless source. The Cisco VN 5900 and VN 5902 Video Networking Systems perform a wide range of video processing and adapt the streams to any standards-based digital broadband network.
The Cisco PS5171 QPSK Receiver/Demodulator complements a complete TV content redistribution solution, by receiving and demodulating audio and video streams from satellites or terrestrial-based wireless networks. The Cisco PS5180 CA Descrambler/Multiplexer descrambles any or all of the video signals from a single MPEG-2 Multiprogram Transport Stream (MPTS).
The Cisco PS5171 QPSK Receiver/Demodulator supports Binary Phase Shift Keying (BPSK), Offset Quadrature Phase Shift Keying (OQPSK), and Quadrature Phase Shift Keying (QPSK) modulation schemes, and accepts L-band signals at data rates up to 57 Mbps. After demodulating the audio and video streams, the Cisco PS5171 QPSK Receiver/Demodulator sends the signals in Digital Video Broadcast/Access Server Integration (DVB/ASI) format to the system's descramblers or to MPEG-2 multiplexers for further processing. Alternatively, it outputs the signals through BNC connectors.
Table 1 is a summary of the Cisco PS5171 QPSK Receiver/Demodulator features and benefits.
The Cisco PS5180 CA Descrambler/Multiplexer receives transport streams from the Cisco PS5171 QPSK Receiver/Demodulator or from any Asynchronous Transfer Mode (ATM), IP, or IP over ATM network. The descrambled output streams are channeled to an input/output (I/O) or to one of the system's network adaptation interfaces. The Cisco PS5180 CA Descrambler/Multiplexer can also demultiplex the descrambled stream into multiple Single-program Transport Streams (SPTS), for direct adaptation to ATM, IP, or IP over ATM networks. The Cisco PS5180 CA Descrambler/Multiplexer accepts up to six Conditional Access (CA) Digital Video Broadcasting Common Interface (DVB/CI) Personal Computer Memory Card International Association (PCMCIA) descrambler modules supplied by a TV content provider. The Cisco PS5180 CA Descrambler/Multiplexer supports all major digital television scrambling systems.
